Description:
5.6 automatically adjusts innodb_thread_sleep_delay, so the values after startup may change and be different from what is in the my.cnf file.

This is a great feature and well documented under

http://dev.mysql.com/doc/refman/5.6/en/innodb-performance.html

but the documentation on the system variable itself doesn't mention the new feature

http://dev.mysql.com/doc/refman/5.6/en/innodb-parameters.html#sysvar_innodb_thread_sleep_d...

I think the sysvar documentation should cross-reference the other doc in order to avoid confusion (I was wondering where innodb_thread_sleep_delay values come from after playing around with 5.6).

How to repeat:
Start 5.6.10 mysqld with different my.cnf values for innodb_thread_sleep_delay and compare to output from

show variables like '%innodb_thread_sleep_delay%';

Suggested fix:
http://dev.mysql.com/doc/refman/5.6/en/innodb-parameters.html#sysvar_innodb_thread_sleep_d...

should cross-reference
